Ok what was it then...I could answer it....well depends what type of question it is
Answer:
You can find surface area by finding the area of all the faces and adding them all together.
Hope this helps!!!
Step-by-step explanation:
By rounding each number to the nearest whole number is 23.5
Given,
Estimate 38¼ - 14¾
and, by rounding each number to the nearest whole number.
Now, The solution is :
=38¼ - 14¾ = 153/4 - 59/4
=> 
=> 94/4
=> 23.5
Estimation a number to the nearest whole number:
To round a number to the nearest whole number, you have to look at the first digit after the decimal point. If the digit is less than 5 (1, 2 , 3, 4) we don't have to do anything, but if the digit is 5 or greater (5,6,7,8,9) we must round up.
Hence, By rounding each number to the nearest whole number is 23.5

Answer:
80°, 40° and 60°
Step-by-step explanation:
Name the second angle X and the first angle to 2X (because it is twice the measure of angle number two) and the third angle to 20°+X (because it was 20° more than the second angle)
so we will have an equation of
180°=2x + x + (20°+x)
160°=4x
40°=x
so the second angle is 40° as it is represented by just one X
therefore the first angle which is twice the measure is 80° and the third angle which is 20° more is 60°. hope that helps!
4x-y
x= 5
y= 6
replace in the ecuation above:
4•5-6= 20-6= 14
